    (MDPI, 2026) Wielbo, Jerzy; Podleśny, Janusz; Podleśna, Anna; Kidaj, Dominika; Sroka-Bartnicka, Anna; Klikocka, Hanna
    The development of new methods enhancing the growth and yield of cereals is still needed in crop production due to their great importance in human diet and as livestock fodder. In our study, new fertilizer-biostimulators with micro- and macroelements and extract containing lipochitooligosaccharides (LCOs) produced by Rhizobium leguminosarum bv. trifolii were used for stimulation of growth of barley and triticale in greenhouse conditions. The preparations were applied at the tillering and shooting stages, whereas plant traits were studied at flowering and at full maturity. The best results were recorded after the joint treatment of the plants with LCOs and mineral fertilization. The application of such a mixture significantly increased the length and mass of roots at flowering in both studied species. A beneficial effect of the treatment was also observed in barley and triticale yields. At full maturity, the grain mass per plant was significantly enhanced, which was the effect of an increased number of grains per ear and increased mass of 1000 grains.

    Impact of Nitrogen and Sulphur Fertilisation on Phosphorus and Silicon Content and Uptake by Biomass of Spring Wheat
    (MDPI, 2026) Klikocka, Hanna; Podleśna, Anna; Podleśny, Janusz
    Nitrogen and sulphur are among the most important plant nutrients (along with C, H, and O) and the main elements comprising the organic substance of plants. In this study, it is assumed that light soils (Cambisols) do not naturally meet the nitrogen and sulphur needs of spring wheat and, consequently, impact the phosphorus and silicon content in the plant biomass. Therefore, to determine the effect of N and S on the content and uptake of these elements at specific growth stages (BBCH 30–31: in leaves, BBCH 55–59: in whole plants, BBCH 89–90: in grain and straw), a three-year field experiment was conducted using different doses of nitrogen (0, 40, 80, and 120 kg ha−1) and sulphur (0, 50 kg ha−1). The results show that fertilisation with N and S had a significant effect on increasing the content and uptake of P and Si by phytomass in the phenostages studied. In general, as the N fertilisation dose increased, the yields of phytomass and grain increased. A beneficial effect of S on increases in green weight, straw, and spring wheat grain was found. A significant effect of N and S fertilisation on the growth of the Si:P ratio in individual parts of plants in the studied stages was also observed. A significant positive correlation between P and Si content was proven, indicating that the two elements do not act antagonistically towards each other. In contrast, a negative correlation was observed between the P content in plants and their Si uptake. Si is taken up more strongly by plants under conditions of N and S fertilisation, as evidenced by the increase in the Si:P ratio and the fact that plants accumulated on average 3.5 times more Si than P. The highest Si content was found in the green parts of plants in the BBCH 30–31 and BBCH 55–59 stages, while in BBCH 89–92, straw had nearly half that amount and grain contained a thousand times less silicon.

    Spring rye as a source of biomass and carbon in the soil
    (Institute of Agrophysics, Polish Academy of Sciences, 2024) Klikocka, Hanna; Podleśna, Anna; Narolski, Bartosz; Podleśny, Janusz
    The aim of the experiment was to determine the mass yield and amount of total carbon accumulated by spring rye biomass in individual stages of growth determined according to the BBCH scale (Biologische Bundesanstalt, Bundessortenamt und CHemische Industrie): BBCH 30–31 – leaves, BBCH 55–59 – whole plants, BBCH 89–92 – grain and straw). The required results were obtained by conducting a field experiment (2009-2011) which tested the effect of the application of nitrogen (0,30, 60, 90 kg ha−1) and sulphur (0, 40 kg ha−1) on biomass yield, carbon content and accumulation, and also the C:N ratio. N application in the amount of 60 and 90 kg ha−1 was shown to have the most beneficial effect on biomass yield at each stage of growth. Carbon was accumulated in the amount of 1 294 kg ha−1 by the leaves (BBCH stage 30–31), 2 365 kg ha−1 by the whole plants (BBCH 55–59), 1 334 kg ha−1 by the grain BBCH 89–92), and 2 062 kg ha−1 by the straw (BBCH 89-92). The total accumulation of carbon by the dry matter of grain + straw increased up to the application rate of 90 kg N ha−1 following the addition of sulphur. The average total accumulation of C was 3 408 kg ha−1. The unit accumulation of carbon was reduced following the application of 30 kg N ha−1, but increased significantly with the level of nitrogen applied, averaging 892.7 C t−1. In general, it may be concluded that under conditions without manure application, ploughing the green matter and straw of spring rye is a good source of carbon in the soil, and is furthermore a technique aimed at limiting global warming by reducing greenhouse gases emissions.

    The effect of soil tillage and sulphur fertilisation on content and ratios of macronutrients in the grain of spring triticale
    (Czech Academy of Agricultural Sciences, 2025) Klikocka, Hanna; Podleśna, Anna; Narolski, Bartosz; Podleśny, Janusz
    The aim of the experiment was to determine the yield, content and uptake of macronutrients and their ratio in spring triticale, Milewo cultivar. The field experiment was conducted in the years 2014–2016 on Cambisols. The first experimental factor was a system of soil tillage (traditional (TRD) and reduced (RED)), and the second was sulphur fertilisation (0,25 and 50 kg S/ha). Based on the study, it was found that the application of conventional tillage and the addition of sulphur fertilisation to NPK significantly increased spring triticale grain yield. The application of reduced tillage positively affected the increase in content and uptake in grain dry matter (DM) of N, S, P, K, Mg and Ca. Adding sulphur (S) to NPK fertilisation favourably increased the content and uptake of N, S, Mg, and Ca and did not affect the content of P and K. The application of reduced tillage expanded the ionic ratio of N : S, P : S while it narrowed the N : P ratio. However, the tillage system did not affect the ionic ratios Ca : P, K : Mg, K : (Ca + Mg) and molar K : (Ca + Mg). Adding sulphur to NPK fertilisation narrowed the N : S and P : S ratios while expanding the N : P and Ca : P ratios. Weather conditions during the 2016 growing season (relatively dry, k = 1.71) favoured spring triticale yield and uptake with dry grain weight of N, S, P, Mg and Ca. The highest N, S, P, K and Ca content in grain dry matter was shown in the 2014 season (relatively humid, k = 1.96). Numerous correlations were found between grain yield and the content, uptake and reciprocal ratios of elements in grain.

    The Influence of Foliar Application of Nod Factors (LCOs) and Microelements on the Growth, Development, and Yield of Peas (Pisum sativum L.)
    (MDPI, 2025) Podleśny, Janusz; Wielbo, Jerzy; Podleśna, Anna; Klikocka, Hanna; Kidaj, Dominika
    Peas are a popular crop grown in Poland, but their yields are variable and often low; therefore, new cultivation methods are constantly being sought. In this paper, we present the results of a three-year greenhouse study examining the effect of preparations containing rhizobial Nod factors and/or selected microelements (B, Cu, Fe, Mn, Zn, and Mo) on the physiological parameters, growth, and yield of peas. Pea plants were tested at the flowering stage (BBCH 60), at the green ripe stage (BBCH 75), and at the fully ripe stage (BBCH 90). Leaf area, SPAD, gas exchange parameters, and chlorophyll fluorescence were measured, and the number and mass of root nodules, as well as seed yield and yield components, were determined. The treatment was most effective when Nod factors were used in combination with microelements. The increase in pea yield induced by the application of both components can be attributed to the higher number of pods and seeds per plant because no significant variations were noted in the number of seeds per pod and 1000 seed weight. The number and weight of nodules were significantly correlated with the pea yield, and the value of the correlation coefficients was influenced by the application of both components.
